Background : Abdominal aortic aneurysms (AAAs) was very important in surgical practices. Open surgery has long been the
standard for repair AAA. We conduct this study to determine outcome of open repair AAA in our center.
Objective : To study the outcomes of traditional surgical treatment for AAAs in a large series of patients who underwent open
repair in both non-ruptured and ruptured groups.
Material and Method: From 2002 to 2009, all patients who underwent open repair and graft replacement of non-ruptured
and ruptured AAAs were analyzed. Computerized perioperative data had been supplemented in the buddy scan program with
a retrospective review of hospital charts/outpatient records. The primary outcome was 30-day mortality rate. The secondary
outcomes were the length of hospital stay and the incidence rate of perioperative complications.
Results : During 2002 and 2009, 150 patients (119 men [79.3%], 31 women; mean age, 70+8 years) underwent the repair of
AAAs. These patients were divided into two groups: 115 patients were in the non-ruptured group and 35 patients in the
ruptured group. In non-ruptured group, the 30-day mortality was 4.34% (5 patients) and re-operative rate was 9.57% (11
patients). The complication rate was 37.4% and the post-operative hospital stay was 17 days. Regarding the ruptured group,
the 30-day mortality was 10 from 35 patients (28.6%). The complication occurred in 30 patients (85.7%) and the most
common organ complication was pulmonary (51.4%). The mean post-operative hospital stay was 24 days and the mean ICU
stay was 11 days.
Conclusion : These results show that open repair of non-ruptured AAA maybe a safe procedure. Even in ruptured group, the
outcome at our center was comparable with other studies.
